Abstract

We describe experiments in which single crystals of NaCl, KBr, and KCl are dissolved from below by aqueous solutions containing variable concentrations of the salts. The saturated solution near the solid-liquid interface is gravitationally unstable to turbulent hydrodynamic motion similar to thermal convection. The coupling of the fluid flow with the solid dissolution produces patterns at the solid-liquid interface with a distribution of horizontal and vertical length scales. The rate of mass transfer and the pattern length scales are compared with a turbulent boundary layer model.
